Specification of Letters Patent.

Application filed October 16, 1913. Serial No. 795,557.

To all whom it may concern Be it known that we, KAnL'VoLLnR, a subj ectof the German Emperor, residing at 12 Scharnhorststrasse, Dusseldorf,Germany, and EMIL MtiLLnn, a subject of the German Emperor, residing at27 Fordanstrasse, Dusseldorf, Germany, have invented certain new anduseful Improvements in Protective Shields for Guns; and we do herebydeclare the following to be a full, clear, and exact description of theinvention, such as will enable others skilled in the art to which itappertains to make and use the same.

Protective shields for guns are known in which the opening for thegun-barrel is covered by a sliding plate. This is automatically shiftedwhen the gun barrel is moved. This construction has the disadvantagethat the plate is no longer capable of moving in its guides when it isdamaged by shot or shell. Moreover the plate can only be adapted toslide if it is of straight or circular section. By the invention, theplate is hinged to the protective shield so as to cover the opening forthe gun barrel and is connected by means of links with a piece whichshares the movement of the gun. The use of this hinged plate allows ofthe protecting shield havin any desiredform.

In the accompanying drawings are shown several constructions inaccordance with the invention.

Figure 1 is a cross sectional view of one form of shield in which theplate covering the opening for the gun barrel lies in front of theshield. Fig. 2 is a rear elevation of this form, the gun barrel and itscradle being in section. Fig. 3 is a cross sectional view of a form inwhich the plate is behind the shield. Fig. 4t is a cross sectional viewof a form in which the arrangement is such that the links which transmitthe movement do not come into action until a certain angle of elevationhas been attained.

In the construction shown in Figs. 1 and 2 the shield 03 isconnectedwith the gun carriage in the known manner and for permittingelevation of the gun barrel there is an opening I) inthe shield. Forcovering this opening aplate d is hinged to the shield at 0 and isconnected by'links c with a part of the gun which shares the elevatingmove ment, in this instance with the cradle f, the connection being bymeans of universal joints 9 both on the plate and on the cradle, so thatthe gun barrel may be moved laterally in respect to the stationaryshield. When the gun is elevated, the links 6 raise the plate (Z, asshown in dotted lines in Fig.

1. Thus the plate moves out of the way of the upwardly swinging gunbarrel and permits the latter to move in the opening 6.

v In Fig. 3 the plate cl is hinged to the back. i of the shoulder andmoves rearwardly when the gun is elevated so as to be out of the way ofthe latter. Such a position of'the plate is shown in dotted lines. a

In Fig; 4 the construction is like that of Figs. 1 and 2, in that theplate (Z is hinged to the front face of the shield. In this form thelinks 6 consist of two parts 6, 6 one sliding within the other, a springit being interposed between the parts. This spring abuts at one end on apiston 2' fixed to the end of rod 6 and at its'other end against theplug is which closes the hollow part 6 When the gun barrel is horizontalthe parts of the link have the positionshown in full lines in Fig. &,the spring 72. being compressed. l Vhen the barrel is elevated, forexample into the position shown in dotted lines, the hollow part c ofthe link is pushed upward over the rod 6 without carrying the latterwith it. The first portion of the elevating movement of the gun barreldoes not produce any movement of the hinged plate, there being arelative movement between the rod 6 and part 6 As soon as the latter hasreached the limit of its travel over the rod 6 and the piston 2'contacts wit-h the lower end .ofrpart 6 the two parts, upon a continuedmovement of the gun, will travel in unison and thereby move the plate dout of the way. WVhen the gun barrel is returned to the hori- .zontalposition the part'e of the link returns with it, together with the rod 6and the hinged plate, until the latter rests upon the shield a, andthereafter the'spring is compressed as the return movement is completed.

l/Ve claim as our invention 1. A gun shield having an opening, a hingedplate for extending over said opening, in combination with a gun, andmeans connected to said plate and to said gun for automaticallyoperating said plate in the raising and lowering of the gun.

2. A gun shield having an opening, a

plate hinged to said shield and designed to extend over said opening, incombination with a gun, and links flexibly connected to the plate andalso to the gun to partake of the raising and lowering movements of thelatter. 7

3. A gun shield having an opening, and a hinged plate designed to extendover said opening, in combination with a gun designed to extend throughsaid opening, and links connecting said plate to the gun to partake ofthe raising and lowering movements thereof, said links having yieldinglyconnected portions whereby the plate will not be operated by the linksuntil a certain angle of elevation of the gun has been at tained.

4. A gun shield having an opening, and a KARL VOLLER. EMIL MULLER.
